Additional information
| Significance and Use | ||||
|
4.1 This test method may be used to compare the gloss of porcelain enamel, ceramic, and other finishes or to provide a comparison of their resistance to attack from acid, alkali, or other environmental factors by measurement of gloss loss. |

| 1. Scope | ||||
|
1.1 This test method covers the determination of the specular gloss of porcelain enameled specimens, but may be applicable to other specimens having similar reflection characteristics. This test method may be used to compare the gloss of porcelain enameled specimens or to provide an index of acid or abrasion resistance by measurement of gloss loss. Note 1: Specular gloss is one of several related appearance
attributes that produce the sensation of glossiness. For this
reason, specular gloss measurements may not always correlate well
with visual rankings of glossiness.
Note 2: Improved correlations with visual judgments can
sometimes be achieved by the use of instruments with different
geometries than those specified herein. Refer to Test Method
D523 for 20, 60, and 85-deg
geometries. Values generally cannot be predicated for one geometry
from measurements made with another.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
